IMPROVEMENT IN BOOT=BLACKING MACHINES.

Specification forming part of Letters Patent No. 123,160, dated January30, 1872.

Specification describing a new and useful i Improvement in Boot-BlackingMachine, in-

vented by NATHAN EIsENMANN, ofthe city of New York, in the county andState of New York.

Figure l is a top view of my improved machine. Fig. 2 is a detailvertical section of the same taken through the line x, Fig. 1.

My invention has for its obj ect to improve the construction of theboot-blacking machine for which Letters Patent No. 121,343 were issuedto me November 28, 1871, so as to make it simplerw in construction, lessexpensive in manufacture, and more edective in operation; and itconsists in the construction and combination of various parts of themachine, as hereinafter more fully described.

A is thebox ofthe machine, to the middle part ofthe bottom of which isattached a pedestal, B, upon the top of which the foot rests while theboot or shoe is being operated upon. The middle part of the top of thepedestal B is recessed for the passage of the shaft C, to which areattached the brushes D. by which the sides of the boot or shoe arepolished. The shaft C revolves in bearings in the sides of the box A.One end of the shaft O projects, and to it is attached brushes E,similar to the brushes D, but which may be made coarser than saidbrushes D, and which are designed to brush olf the mud or dust from theboots and shoes before applying the blacking. To the shaft C, near itsother end, is attached a gear-wheel, F, the teeth of which mesh into theteeth of the gear-wheel G. The gear-wheel G is pivoted to the side ofthe box A, and to the projecting end of its journal is attachedthe-crank H, .by which thc machine is operated. 'Io the gear-wheel G isattached a crank-pin, I, to which is pivoted the upper end of the bar J,the other end of which is bent inward, and to it is pivoted theoutwardly-bent lower end of the` bar K, the two bars J K thus forming aU-shaped bar, jointed at its bend, as shown in Fig. 1. The other orupper end of the bar K is securely attached to the brush L, by which therear part of the boot or shoe is brushed, and which is pivoted to andhung from the long crank M formed upon the shaft N, the ends of whichare pivot-ed to the upper part of the sides of the box A. To the samecrank-pin I of the gear-wheel G is pivoted the end of the bar O, theother end of which is bent inward and then forward, and to it is pivotedthe rear end of the bar P, which is bent inward and then forward; andits other or forward end is attached to the brush Q, by which the upper'and forward parts of the boot or shoe are polished. The brush Q ispivoted to and suspended from the crank R form ed upon the shaft S, theends of which. are pivoted to the upper part of the sides of the box A.The brushes L Q are made in two parts, connected to each other by guideor dowel-pins or bolts, so that the `said brushes may be expanded orcontracted according as a larger or smaller boot or shoe is to beoperatedV upon.

The bristles thatform the brushes, and which are not shown in thedrawing, should be so arranged as to cover and operate upon the entiresurface of the boot or shoe, whether the said brushes be expanded orcontracted.

By this construction of the machine the brushes, by the combined actionof the suspension-cranks and operating-bars, will receive the necessarymovement-s to cause them to operate properly upon the boot or shoe to beblacked or polished.

If desired, a stand or holder for the blackin g-box or blaoking may beconnected with or attached to the box A so as to have the blacking in aconvenient position.

Having thus described my invention, I claim as new and desire to secureby Letters Fatent- 1. The combination of the pivoted or jointed bars J Kand O P with the brushes L Q and crank-pin I attached to the gear-wheelG, substantially as herein shown and described, and for the purpose setforth.

2. The crankn rock-shafts M N and R S in combination with the brushes LQ, pivoted or jointed bars J K and O P, crank-pin I, and crankgear-wheel G, substantially as herein shown and described, and for thepurpose set forth.

The above specification of my invention signed by me this 6th day ofDecember. 1871.
